Letters Patent No. 109,029, dated November-8, 1870.

IMPROVEMENT IN DOUBLE AND SINGLE-TREE ATTACHMENTS FOR STREET-CARS.

The Schedule referred to in these Letters Patent and making part of the same.

1, JAMES F, Lowe, of the city of Louisville, county of Jell'ersoiiand State of Kentucky, have invented a certainnew and useful Improvement in aDouble and Single-Tree Attachment for Street, Railroad, and other Cars, of which the following is a specification. The nature of my invention consists in a clevis made from a flat-bar of wrought-iromtbent edgewise, form- I iug aeeircle in front, the hack ends being secured to the under side of the car platform. This clevis has also another flat bar running through the center, one eiidof which is bolted to the front part of the clevis, while the other is bolted to the under-side of the platform, so that, when thus arranged, the clevis forms a stationary rest or slide, on which the double-tree is madeto. work, thereby preventing it from dropping down as 'the ear stops.

'ln the top of this last-named central harthere is a small hook or pin, with the point'turned slightly backward, as an attachment for the double-tree, which drops over it, and is kept in its place by means of another flat hook secured to the baylhe end of which is made to work orera circular slide attached to'the back of the double-tree, which prevents it from rising upol' turning, and can he used also as a convenient means of attaching it to the back end of the car, when necessaiy to draw it backward. The same arrangement'is used on the single-tree when only one horse is required.

.li'iti ing thus fully described the nature of my invention, a more perfect understanding of same may be had by reference to the drawing, in which- Figure 1 represents the front part of the car platform, showing the double-tree attachment.

Figure 2 represents the single-tree to be used when only one horse is required.

In the drawing A is the clevis.

B is central bar.

0 is the hook to which the double-tree is attached.

1) is the fiat hook by which it is kept in its place.

"E is the double-tree.

G G are the singlet-recs.

l 1 are the circular slides on the double-tree E and single-tree H.

J J are the holes in the same.

K is the front of the platform.

The above constitutes a description of the drawing; therefore 7 What I claim as new, and desire to secure by Letters Patent, is-

.The combination of the elevis A, the central bar B with its llooks O and D, the double and single7trecs E and H with their circular slides F F, and the holes J J, substantially as and for the purpose herein set forth.
